Abstract: 808,334. Heat treatment furnaces. BRITISH FURNACES Ltd. June 20, 1957 [July 6, 1956], No. 19465/57. Class 51 (2). A continuous atmosphere furnace has a reciprocable conveyer extending through an opening in a wall into the furnace chamber and sealing means for assisting the formation of a gas-tight seal between at least a part of the wall surrounding the opening and the conveyer. A conveyer 18 resiliently supported for limited longitudinal movement by rods 21 extending through the roof of the furnace 12 is reciprocated by a lever 48 actuated by a motor-driven cam 51, under the control of a spring 52 and a bumper 53. The work is discharged down a shoot 54. In order to reduce the escape of the furnace atmosphere and the inflow of air at the opening 20 through which the conveyer 18 extends an inverted U- section member 65, Fig. 4, is slidably mounted between a bracket 63 and the wall round the opening, and held against the underside of the conveyer 18 by a lever 66 and counterweight 71. A cover 73 attached to the conveyer 18 contacts a sealing member 74, similar to member 65, sliding between the wall and a bracket 75. An asbestos curtain 80 depends from the cover 73. In a modification, Fig. 6, not shown, the counterweight is replaced by a spring, and the cover secured to the conveyer and its co-operating sealing member are replaced by asbestos curtains and a cover supported from the furnace wall. This arrangement allows the size of opening to vary as the level of the conveyer varies with its load. A pipe 81 delivers air under pressure downwardly above the opening and with a pilot flame 83, provides a flame curtain on the escape of an inflammable atmosphere. The furnace 12 is heated by two U-shaped radiant tubes 40 and a W-shaped radiant tube 41 at the discharge end in a plane perpendicular to the movement of the conveyer 18. The U-shaped tubes are fixed at their lower legs.

Abstract: 586,310. Impulse transmitters. SODECO SOC. DES COMPTEURS DE GENEVE. Nov. 22, 1943, No. 19509. Convention date, Nov. 18, 1942. [Class 40 (iv)] In an arrangement for preventing the effective dialling of numbers starting with certain digits, a number of circuits 86 including normally-open cam-controlled contacts 87 ... 90 are provided for shunting the impulse contact 19, one of the circuits being selected by a switch 82 rotated by the dialling of the first digit and the cam-shaft 30 being rotated by the dialling of the second digit. In the case of the first digit 0, a direct shunt circuit 97 is provided. A gear-wheel 26 on the dial shaft 23 meshes with a pair of gear-wheels 27, 28 loose on shafts 29, 30 which are held against rotation in one direction by detents brought into engagement with ratchets 33, 57 by the lifting of the switchhook 54. By means of a pawl 31 on the wheel 27 and an arrangement of notched discs, Figs. 2-7 (not shown), the first forward movement of the dial is imparted to the shaft 29 which sets the switch 82 and is unaffected by subsequent movements of the dial. By means of a somewhat different arrangement, Figs. 8-15 (not shown), only the second forward movement of the dial is imparted to the cam-shaft 30. In addition, a pawl 98 mounted on the wheel 26 rotates a shaft 100 one step for each digit. This shaft carries a cam 102 which serves to short-circuit the impulse contact 19 after the full number of digits have been dialled, and a cam 101 which completes a shunt circuit after the second digit if the first digit is 1, this circuit including a selected contact of the switch 82. The shafts 29, 30, 100 are returned to normal by spring action when the receiver is replaced on the switch-hook 54. A switch 120 may be provided for disabling the shunt circuits under certain conditions.
